Balancing the Need for High Capacity and the Desire for Fast Charge for Batteries in Consumer Electronics

摘要

After almost 30 years of CCCV Charge, lithium-ion chemistry is reaching its energy density ceiling (for now). 1. The next best thing to having more capacity is having capacity replenished faster 2. Developers are working on fast charge concepts that are best when they are combined with cell modifications for accepting faster charge 3. The charge stresses (high current and high cut-off voltage) must be removed at some stage of the cell's life.
